NumPy arrays are capable of holding multidimensions of data. Just like a single dimension array, calculations will occur on each element within the array and the array can only hold a single data type within it. Explore how to create and use mutidimensional arrays with additional functionality using the NumPy library.
What is array slicing in NumPy? Well this is called slicing our array, which is just as it sounds we are slicing up our array to whatever it is we need. So, previously with array indexing we were selecting a single index, now we are selecting between two indexes.

Welcome to this video series on python tools for data science and machine learning and in this video we're going to talk about splitting and slicing NumPy arrays. We need to understand NumPy arrays if we want to have data science and machine learning in python programming language. Slicing numpy arrays helps in making sure that we can extract data from numpy arrays in a desired form Splitting is another way of extracting data from the NumPy arrays where we can split the numpy arrays horizontally as well as vertically. Hope this video will help you in understanding the NumPy arrays.

In this tutorial, we will learn about Indexing and slicing in Numpy. Indexing in Numpy Python for data analysis. “Indexing” means referring to an element of an iterable by its position within the iterable. To retrieve an element of the list, we use the index operator ([]): Slicing: “Slicing” means getting a subset of elements from an iterable based on their indices. A slice is a subset of list elements. In the case of lists, a single slice will always be of contiguous elements. Slice notation takes the form Indexing and Slicing in the 1D array( One Dimensional Array) in NUMPY PYTHON. Indexing and Slicing in the 2D array( Two Dimensional Array) in NUMPY PYTHON. Indexing and Slicing in the 3D array( Three Dimensional Array) in NUMPY PYTHON. Access Complete Numpy Playlist: 🤍 Access complete code on GitHub: 🤍 This course is divided into some parts: 1.
